<p>Issue here: <a href="https://github.com/rust-lang/rust/issues/76490">https://github.com/rust-lang/rust/issues/76490</a><br>
Obviously the microbenchmarks are speaking about runtime performance (and so a lot of it is about the consumers of <code>format_args!</code>) but I am willing to bet a tenner that this is also potentially meaningful for compilation time. Just thought I'd post a heads up and/or ask if anyone had any thoughts on it.</p>
